Description

Technical Field

[0001] The present application relates to the technical field of bag dust collectors, and in particular to a pulse long bag dust collector that is convenient for replacing filters. Background Art

[0002] The pulse long bag dust collector uses long bags as filter elements, and removes dust accumulated on the bags through pulse jet technology, thereby achieving the purpose of dust removal. Its working principle mainly relies on the combination of the filtering effect of the bags and the pulse jet cleaning technology. Generally speaking, the filter bags in the dust collector are mainly used to filter out tiny particles in the gas to achieve the purpose of purifying the air, while the filter screen can initially filter out large particles in the gas, reduce the load pressure of subsequent filter bags, and protect the filter bags from direct impact of large particles. The two have different uses and cooperate with each other to complete the filtration of the air. The connection structure of the existing filter screen is relatively complex, and it is more troublesome to disassemble and assemble. In addition, the filter screen may scrape the track when disassembling, thereby affecting the normal filtering effect and capacity of the device. Utility Model Content

DETAILED DESCRIPTION

[0024] In order to make the technical means, creative features, objectives and effects of the utility model easier to understand, they are further explained below in conjunction with specific implementation methods.

[0025] Example 1: A pulse long bag dust collector that is easy to replace the filter screen, see Figures 1 to 8 , including a dust removal bin 1, a support ring 14, a filter screen 17, an external fixing block 15 and a connecting rod 121, a partition 7 is fixedly connected to the upper inner wall of the dust removal bin 1, and eight groups of semi-circular outer filter slots 8 are penetrated on the surface of the partition 7, and an inner filter slot 9 is penetrated on the surface of the partition 7 inside the outer filter slot 8, and a connecting rod 121 is fixedly connected to the bottom of the partition 7 outside the outer filter slot 8, and the bottom of the connecting rod 121 is fixedly connected to the bottom of the bottom plate 13, and the left and right sides of the top of the bottom plate 13 are fixedly connected to the vertical rod 12, and the top of the vertical rod 12 is fixedly connected to the bottom of the partition 7 in the central area of ​​the left and right ends of the two outer filter slots 8 The bottom surface of the support ring 14, the bottom plate 13 and the outer filter tank 8 can constrain the filter frame 16 to make it stable, avoiding the problem of impacting and scratching the filter bag 11 during the replacement of the filter screen 17, affecting the normal filtering effect and function; the bottom of the support ring 14 is fixedly connected to two filter frames 16, and the inner side of the filter frame 16 is detachably connected to the filter screen 17, and the top surface of the support ring 14 on one side of the outer fixing block 15 is fixedly connected to the handle 18. When replacement is needed, you only need to open the top plate 5, hold the handle 18 to directly pull out the support ring 14 and the filter frame 16 to take out the filter screen 17, which is very convenient to operate.

[0026] It is worth noting that if Figure 5 As shown, both sides of the top of the support ring 14 are fixedly connected with external fixing blocks 15, and the surface of the external fixing blocks 15 is threadedly connected with bolts. The external fixing blocks 15 can fix the support ring 14 on the surface of the partition 7 to ensure stability.

[0027] It is worth noting that Figure 5 As shown, the filter frame 16 is movably inserted into the inner side of the outer filter slot 8, and the spacing between the filter frames 16 is consistent with the width of the central area at the left and right ends of the two outer filter slots 8. When the filter frame 16 is fully inserted, the outer filter slot 8 can be completely blocked by the filter frame 16 and the support ring 14, thereby preventing dust from leaking out of the outer filter slot 8.

[0028] It is worth noting that if Figure 1 and Figure 2As shown, the top edge of the dust removal bin 1 is movably connected with a top plate 5, and eight pulse air pipes 6 are fixedly connected to the surface of the top plate 5. The pulse air pipes 6 are located directly above the corresponding inner filter tank 9. When the top plate 5 is fully closed, the pulse air pipes 6 are directly facing the inner filter tank 9 below. When cleaning is required, the pulse air pipes 6 can directly pay attention to the filter bag 11 for cleaning. The bottom of the dust removal bin 1 is fixedly connected and connected to the collecting bin 2. The left side wall of the collecting bin 2 is provided with an air inlet 3, and the right side wall of the dust removal bin 1 above the partition 7 is provided with an air outlet 4.

[0029] It is worth noting that if Figure 7 and Figure 8 As shown, a gasket 10 is movably inserted into the inner side of the inner filter tank 9, both side edges of the top of the gasket 10 are fixedly connected with internal fixing blocks 1001, and a filter bag 11 is fixedly connected to the bottom of the gasket 10. When the filter bag 11 needs to be replaced, the gasket 10 can be directly pulled out of the inner filter tank 9.

[0030] In actual use, air is drawn into the dust removal bin 1 and the collection bin 2 through the inlet, and after being filtered by the filter screen 17 and the filter bag 11, it finally leaves through the air outlet 4. The filter screen 17 can be easily replaced through the outer filter tank 8, the support ring 14, the filter frame 16 and the filter screen 17. The filter screen 17 is installed on the filter frame 16, and the filter frame 16 is inserted into the outer filter tank 8. When replacement is needed, it is only necessary to open the top plate 5, hold the handle 18 and directly pull out the support ring 14 and the filter frame 16 to take out the filter screen 17. The operation is very convenient, and the filter screen 17 is set on the outside of the filter bag 11, which can be At the same time, it withstands the impact of pulse airflow for cleaning, ensuring the filtering efficiency and practicality of the device. At the same time, the filter frame 16 can be constrained by the connecting rod 121, the vertical rod 12 and the bottom plate 13. When the filter frame 16 is fully inserted, the bottom of the filter frame 16 will be inserted into the annular groove on the surface of the bottom plate 13 for limiting, thereby preventing the filter frame 16 from shaking and increasing its stability. The width of the filter frame 16 is consistent with the width of the outer filter slot 8, so that it can be kept vertical during insertion and removal, avoiding the problem of impacting and scratching the filter bag 11 during the process of replacing the filter screen 17, affecting the normal filtering effect and function.

[0031] It should be noted that, when cleaning, the cleaning controller issues a cleaning command, first cutting off the filtering airflow; then, the cleaning controller sends a signal to the pulse valve 601, and as the pulse valve 601 sends the high-pressure reverse airflow used for cleaning into the bag, the filter bag 11 swells rapidly and vibrates violently, causing the dust on the outside of the filter bag 11 to fall off, thereby achieving the purpose of cleaning. The pulse valve 601 is connected to the pulse air pipe 6, and the pulse valve 601 is a well-known device that can be purchased directly on the market. It is only used here, and its structure and function are not improved, so it will not be described in detail.
